Abstract: A wearable infusion system for delivering a fluid medication such as insulin to a patient through a needle, cannula or catheter (28). The infusion system includes a medication-filled elongate, thin-walled tubular reservoir (40) and a positive displacement metering assembly (22) operated by a power source under the control of a controller such as a microprocessor (24). The positive displacement metering assembly (22) draws the reservoir (40) inwardly between squeeze surfaces (56) which forces the medication toward the remote end where it discharges through an associated cannula, catheter or needle (28) into a patient. The rate and frequency at which the metering assembly is operated controls the rate and frequency at which the medication is delivered to the patient. The tubular reservoir defines a plurality of loops (48) so that a maximum amount of fluid medication may be disposed in a housing.

Abstract: The machine e.g. a fan, has a cylindrical housing (2) around a rotor (1), and a guide wheel (3) downstream of the rotor (1). Upstream or downstream of the latter there is a further auxiliary rotor (4), co-axial with rotor (1), and having blades of a smaller radial size. In the part of the hub of rotor (1) where flow separation is likely, for decreasing the deflection of the relative flow and for this reason for decreasing the blade grid loading, the supply of energy is decreased in the profile sections in question by decreasing the change in the circumferential velocity component of the absolute flow between the inlet and outlet of rotor (1). The auxiliary rotor (4) supplies further energy in these profile sections for keeping substantially constant the design- dependent energy amount in all blade sections. In a modification boundary layer aspiration is used in the region of potential flow separation. Rings (5,9) may be provided. <IMAGE>

A cross beam (6) is movably joined to the bogey frame (4, 5). It is borne by spring components (7) and can rotate around a pin (8). Spring components (14) between the pin (8) and the beam (6) and the other spring components (7) allow sprung side movement between the beam (6) and the frame (4, 5).  A wagon body (13) is supported by additional springs (12), resting on a cradle with a tilt function (9) hanging from the beam (6).

Abstract: Copper sulfide ores are processed by a unique series of steps to produce blister copper, while attaining long sought advantages. An initial smelting step is carried out in any desired manner, e.g. according to conventional practice, to produce a molten, copper sulfide matte or white metal. This matte or white metal is then solidified and subjected to a size-reduction step to produce solid particles capable of being injected into a converting vessel in a stream of oxygen, either pure oxygen or air significantly enriched with oxygen. With the matte or white metal injected in this manner, the converting reaction may be carried out on an autogenous basis, with continuous evolution of substantially undiluted SO2 gas capable of being liquified for use in the production of elemental sulfur or sulfuric acid or for disposal so as to avoid atmospheric contamination. The usual fugitive gas emissions resulting from the handing and transporting of molten matte in conventional ways are almost completely avoided, and continuous optimized operation of the converting vessel is achieved independently of operation of the smelting step, making it possible to eliminate the often-resorted-to close coupling of smelting and converting furnaces and affording unusual freedom in plant layout.

Abstract: Method of improving the conveying properties of a particulate fuel in a fluidized bed combustion plant and a combustion plant for carrying out the method. The improved conveying properties are achieved by at least surface drying of the fuel. A calcium-containing bed material is withdrawn from the bed under such conditions that the bed material is calcined to form CaO. The withdrawn bed material is crushed and mixed with fuel, whereby the CaO absorbs water from the fuel in an exoergic reaction forming calcium hydroxide, Ca(OH)2. The heat released by this reaction evaporates moisture from the fuel. The fuel particles will have reduced surface moisture which reduces the risk of clogging during the pneumatic feeding of the fuel to a combustion chamber. Due to the intimate contact between the fuel particles and the crushed bed material, the tendency towards reaction between sulfer in the fuel and the bed material is increased. To intensify the drying process drying gas may be supplied while mixing fuel with the withdrawn bed material.
